- In sys/ofed/drivers/infiniband/core/cma.c, an enum struct member is
interpreted as an int, so cast it to an int.
- In sys/ofed/drivers/infiniband/core/ud_header.c, initialize the
packet_length variable in ib_ud_header_init(), to prevent undefined
behaviour.
- In sys/ofed/drivers/infiniband/ulp/sdp/sdp_rx.c, call rdma_notify()
with the correct enum type and value.
- In sys/ofed/include/linux/pci.h, change the PCI_DEVICE and PCI_VDEVICE
macros to use C99 struct initializers, so additional members can be
overridden.

Allow textdumps to be called explicitly from DDB.
If "dump" is called in DDB and textdumps are enabled then abort the
dump and tell the user to turn off textdumps.
Add options TEXTDUMP_PREFERRED to turn textdumps on by default.
Add options TEXTDUMP_VERBOSE to be a bit more verbose while textdumping.

removal of the page queues lock from this pmap.
Replace all uses of the page queues lock by a R/W lock that is private

more appropriate named kernel options for the very distinct
send and receive path.
"options SOCKET_SEND_COW" enables VM page copy-on-write based
sending of data on an outbound socket.
NB: The COW based send mechanism is not safe and may result
in kernel crashes.
"options SOCKET_RECV_PFLIP" enables VM kernel/userspace page
flipping for special disposable pages attached as external
storage to mbufs.
Only the naming of the kernel options is changed and their
corresponding #ifdef sections are adjusted. No functionality
is added or removed.

In particular, do not lock Giant conditionally when calling into the
filesystem module, remove the VFS_LOCK_GIANT() and related
macros. Stop handling buffers belonging to non-mpsafe filesystems.
The VFS_VERSION is bumped to indicate the interface change which does

In the while SMBFS regular users can use FUSE interface and smbnetfs
port to work with their SMBFS partitions.
Also, there are ongoing efforts by vendor to support in-kernel smbfs,
so there are good chances that it will get relinked once properly locked.
This is not targeted for MFC.
